FG40 is an electro-permanent magnet (EPM) designed for aerospace, robotic, and industrial applications. It combines the advantages of electro- and permanent magnets by being able to switch between the on-state and off-state on demand (like an electromagnet); while consuming zero power in either state (like a permanent magnet).

The device supports the following communication interfaces:

Cyphal/CAN FD control with diagnostic telemetry;
RCPWM control input (A-suffix models only);
voltage level control input (A-suffix models only);

For more information, refer to the product home page and the reference manual.

Variants

FG401M - optimized for cost-sensitive applications.
FG401MA - for systems without CAN bus; supports RCPWM and voltage level control/feedback.
FG402M - optimized for mission-critical applications.
